Description

Technical Field

[0001] This utility model relates to the field of lung function training technology, specifically to a respiratory lung function training device. Background Technology

[0002] The lungs play a vital role in the human body. They are responsible for respiration, constantly inhaling fresh air and exhaling stale air, expelling old air and taking in new air, thus facilitating gas exchange between the body and the external environment to maintain human life activities. For some patients with lung diseases, lung rehabilitation training equipment is needed.

[0003] Existing lung capacity training devices typically only offer one training mode: expiratory or inspiratory training. They cannot simultaneously train both expiratory and inspiratory functions. Furthermore, the lung capacity of individuals varies greatly. For example, the lung capacity of professional singers is much larger than that of ordinary patients. Therefore, ordinary lung capacity training devices, due to their fixed training difficulty, cannot meet the needs of different groups of people at the same time, resulting in insufficient training adaptability.

[0004] Therefore, it is necessary to invent a respiratory function training device to solve the above problems. Summary of the Invention

[0005] This invention addresses the aforementioned problems by providing a respiratory pulmonary function training device, which solves the issue of limited applicability for lung capacity training.

[0006] The technical solution adopted by this utility model is as follows: it includes a rectangular cylinder, a conical air nozzle, a movable plug, a damping spring, and an adjustment component; the front end of the rectangular cylinder is provided with a connecting hole, the conical air nozzle is a disposable air nozzle, which is sealed and detachably installed at the interface of the connecting hole, the movable plug is sealed and slidably disposed in the rectangular cylinder, the damping spring is connected between the movable plug and the inner wall of the rear end of the rectangular cylinder, and the adjustment component is disposed in the rectangular cylinder.

[0007] Furthermore, preferably, the control component includes a movable plate, a return spring, a slider, and a connecting rod; a first groove is formed on the rear inner wall of the rectangular tube, and a second groove is formed on the front inner wall of the rectangular tube; the movable plate is slidably disposed in the first groove, and the movable plate has multiple vent holes, the number of which gradually decreases from the center to the front and rear sides; a rectangular groove is formed on the side wall of the rectangular tube located at the center of the first groove, and the rectangular groove communicates with the interior of the rectangular tube through the vent holes; the return spring is connected between the movable plate and the rear inner wall of the rectangular tube; the slider is slidably disposed in the second groove; and the connecting rod slides through the side wall of the rectangular tube, with one end of the connecting rod fixed to the slider and the other end fixed to the movable plate.

[0008] Furthermore, preferably, the movable plug is in intermittent contact with the moving plate, and the movable plug is in intermittent contact with the slider.

[0009] Furthermore, preferably, the force of the damping spring is much greater than the force of the return spring.

[0010] Advantages of this utility model:

[0011] By using the control components, it is possible to conduct exhalation and inhalation training simultaneously. On the other hand, it is possible to conduct different levels of training for ordinary patients and professional singers. It can automatically adjust the difficulty of lung capacity training according to people with different lung capacity, thereby improving training adaptability.

[0020] refer to Figures 1 to 3 A respiratory pulmonary function training device includes a rectangular cylinder 1, a conical mouthpiece 2, a movable plug 3, a damping spring 4, and an adjustment component 5. The rectangular cylinder 1 has a connecting hole 11 at its front end. The conical mouthpiece 2 is a disposable mouthpiece that is sealed and detachably installed at the interface of the connecting hole 11. The movable plug 3 is slidably disposed within the rectangular cylinder 1. The damping spring 4 is connected between the movable plug 3 and the inner wall of the rear end of the rectangular cylinder 1. The adjustment component 5 is disposed within the rectangular cylinder 1.

[0021] In one embodiment of this utility model, the control component 5 includes a movable plate 51, a return spring 52, a slider 53, and a connecting rod 54; a first groove 12 is provided on the rear inner wall of the rectangular tube 1, and a second groove 13 is provided on the front inner wall of the rectangular tube 1; the movable plate 51 is slidably disposed in the first groove 12; the movable plate 51 has a plurality of vent holes 511, the number of which gradually decreases from the center to the front and rear sides; a rectangular groove 14 is provided on the side wall of the rectangular tube 1 located at the center of the first groove 12; the rectangular groove 14 communicates with the interior of the rectangular tube 1 through the vent holes 511; the return spring 52 is connected between the movable plate 51 and the rear inner wall of the rectangular tube 1; the slider 53 is slidably disposed in the second groove 13; and the connecting rod 54 slides through the side wall of the rectangular tube 1, with one end of the connecting rod 54 fixed to the slider 53 and the other end fixed to the movable plate 51.

[0022] It should be noted that the rectangular tube 1 is made of transparent material, and scale lines are set on the surface of the rectangular tube 1.

[0023] In one embodiment of this utility model, the movable plug 3 is in intermittent contact with the moving plate 51, and the movable plug 3 is in intermittent contact with the slider 53.

[0024] Specifically, this device can be used for expiratory training. First, for ordinary patients, the patient slowly exhales through the conical mouthpiece 2. The exhaled air creates positive pressure at the front of the movable plug 3, which pushes the movable plug 3 backward and compresses the damping spring 4. The damping of the damping spring 4 can exercise the patient's expiratory muscles, thus completing one expiratory training cycle. After exhalation, the position of the movable plug 3 at the scale line is observed and recorded. After completion, the patient's mouth is removed from the conical mouthpiece 2, and the movable plug 3 returns to its initial position under the elastic force of the damping spring 4, facilitating repeated expiratory training. Second, for professional singers, the patient slowly exhales through the conical mouthpiece 2. Initially, like ordinary patients, the exhaled air pushes the movable plug 3 backward and compresses the damping spring. Spring 4, because the standard value of a professional singer's vital capacity is greater than that of an ordinary person, the patient continues to exhale, and the movable plug 3 will squeeze the moving plate 51, causing the moving plate 51 to move backward. During this process, the number of ventilation holes 511 connected to the rectangular groove 14 gradually decreases, so the outflow of gas behind the movable plug 3 is smaller. In other words, the further the moving plate 51 moves backward, the greater the damping effect of the ventilation holes 511 on the gas release behind the movable plug 3, that is, the more difficult it is for the movable plug 3 to move backward, so that the vital capacity of professional singers can be trained to different degrees. After completing one training session, the patient's mouth is removed from the conical mouthpiece 2, and the movable plug 3 returns to its initial position under the elastic force of the damping spring 4. At the same time, the elastic force of the return spring 52 can push the moving plate 51 back to its initial position, so as to facilitate repeated exhalation training.

[0025] In addition, this device can also be used for inhalation training. Firstly, for ordinary patients, the patient slowly inhales into the conical mouthpiece 2, creating negative pressure at the front of the movable plug 3. This pulls the movable plug 3 forward and stretches the damping spring 4. The damping of the damping spring 4 exercises the patient's inhalation muscles, completing one inhalation training cycle. After inhalation, the position of the movable plug 3 at the scale mark is observed and recorded. After completion, the patient removes their mouth from the conical mouthpiece 2, and the movable plug 3 returns to its initial position under the elastic force of the damping spring 4, facilitating repeated exhalation training. Secondly, for professional singers, the patient slowly inhales into the conical mouthpiece 2. Initially, like ordinary patients, the inhaled air moves the movable plug 3 forward and stretches the damping spring 4. Due to the lung capacity of professional singers... The lung capacity of the standard value is greater than that of an ordinary person, so the patient continues to inhale. The movable plug 3 will squeeze the slider 53, causing the slider 53 to move forward. This will drive the moving plate 51 forward through the connecting rod 54. During this process, the number of ventilation holes 511 connected to the rectangular groove 14 gradually decreases, so the air flow behind the movable plug 3 is smaller. In other words, the further the moving plate 51 moves forward, the greater the damping effect of the ventilation holes 511 on the inhalation of air behind the movable plug 3, and the more difficult it is for the movable plug 3 to move forward. This allows for different levels of training of the lung capacity of professional singers. After one training session, the patient's mouth is removed from the conical mouthpiece 2, and the movable plug 3 returns to its initial position under the elastic force of the damping spring 4. At the same time, the elastic force of the return spring 52 can pull the moving plate 51, the connecting rod 54, and the slider 53 back to their initial positions to facilitate repeated inhalation training.

[0026] In one embodiment of this utility model, the elastic force of the damping spring 4 is much greater than that of the return spring 52. That is to say, during breathing training, the damping effect of the return spring 52 is negligible for professional singers, thus avoiding interference of the return spring 52 with the magnitude of the damping force during training.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
